SPECIFIGATION forming part of Letters Patent No. 740,964, dated October6, 1903. Application filed November 13, 1902. serial No. 131 ,077. (Nomodel.)

To wZZ whom it may concern:

Be it known that I, KARL WINTscH, J r., a citizen of the United States,residing at Newark, in the county of Essex and State of NewJersey,haveinvented and produced a new and original Improvement inButchers Blade- Bone Extractors; and I do hereby declare the followingto be a full, clear, and exact descrip tion of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe figures of reference marked thereon,which form a part of thisspecification.

It will be understood that butchers and dealers in meats are oftenrequired in preparing a shoulder of lamb, veal, or the like forhousehold purposes to pull out the blade-bone thereof in order to form apocket which can be stuffed by the cook with suitable condiments.

The objects of this invention are to provide a hook especially adaptedfor drawing out or extracting the bladebone from a piece of meat, asthus described; to provide a device of simple and cheap construction andone which will be efiective in its work and not easily gotten out oforder, and to obtain other advantages and results, some of which may bereferred to hereinafter in connection with the description of theworking parts.

The invention consists in the improved butchers blade-bone extractor andin the arrangements and combinations of parts of the same, allsubstantially as will be hereinafter set forth and finally embraced inthe claim.

Referring to the accompanying drawings, in which like figures ofreference indicate corresponding parls in each of the several figures,Figure l is a front view of my improved hook or extractor withablade-bone therein. Fig. 2 is a side view of the same, and Fig. 3 is aplan. Fig. 4: is a front elevation of the hook alone; and Fig. 5 is avertical section of the same on line as, Fig. 4. Fig. 6 is acrosssection of the inclined fingers of the book, as on line y, Fig. 5.

In said drawings, 2 indicates my improved hook, which is preferably bentout of apiece of heavy sheet metal and hasa flat body portion 3, adaptedto be fastened flatwise against a butchers rail or any other suitablesupport. At the lower end of said body part an integral clutchingportion curves forwardly outward and is turned upward and provides aninclined portion 4, diverging from the said body part 3. Said inclinedportion 4 is centrally slotted, as at 5, from its upper end downward andentirely through its curved portion to the base of the plate portion 3,thus forming fingers ll. Said slot 5 is widest at the top and narrowstoward the bottom, being of suitable width to wedgingly receive the neckof a blade-bone 6 at some point be tween its two ends. The walls of thesaid slot, furthermore, are beveled forwardly outward or apart, as at 9,so that a slight lateral movement ofthe blade-bone may be permittedwithout danger of dislodging its head 8 from the hook. A clutchingportion 4 is thus formed, which provides a pair of fingers 11, having anoutwardly-flarin g interval between arid their facing surfaces beveleddownwardly and outwardly apart.

The body-plate 3 is preferably provided for its attachment to thebutchers rail or other support with screw-holes 10, disposed in acentral vertical line coincident in front view with the central line ofthe slot 5, as shown in Fig. 4, whereby access of a screw-driver ispermitted to the screws in setting up the device.

When mounted, with the body-plate 3 in vertical position, my improvedextractor provides a forwardly upwardly inclined wedgeshaped opening toreceive the head of the blade-bone 6, it being understood that saidblade-bone is embedded in a shoulder of meat, with the exception of itshead, and it is desired to catch said head by some gripping means, sothat the butcher by pulling on the piece of meat may free it from thebone. It will be noted that the inclined clutching portion 4 terminatesat its upper end below the upper end of the body-plate 3, and thus asthe bone-head 8 is inserted into the upper large end of the slot 5 itmay engage the said body-plate behind and be guided downward withgreater facility.

While I prefer to make my improved extractor in the exact form shown, itis evident that the base-plate or sppp'orting means for the twodiverging arms might be varied in construction Without departing fromthe spirit and scope of the invention.

Having thus described the invention, what terval and having their facingsurfaces flared I claim as new is downwardly and outwardly.
